Above-mentioned purpose of the present utility model can adopt following technical proposal to realize: a kind of protective device of thermopair; it is characterized in that: described device comprises cooling stick; cooling stick one end is fixed on the seal box on furnace shell surface; be provided with cooling-water duct in the described cooling stick; outside water inlet pipe and water outlet pipe links to each other with cooling-water duct, forms cooling system.
For the side top furnace charge that the stops thermopair damage of pounding to thermopair, the high-temperature part that described protective device is positioned at blast furnace is provided with the flap to downward-extension.
For push and block high-temp. furnace material in the installation process, thermopair is protected, in the thermopair course of work, stop the place ahead high-temp. furnace material to the destruction of thermopair, the end that described protective device is positioned at blast furnace is provided with striker plate.
Can not affect the temperature-measuring results of thermopair in order to ensure the cooling of cooling stick, described cooling stick bottom surface is coated with the heat insulation material of one deck, and leaves the space between heat insulation material and the thermopair.
The high-temperature part that described cooling stick is positioned at stove is copper, is positioned at low-temp. portion and is divided into steel.
The integral body of described cooling stick is copper or steel.
The utility model can be used for the temperature monitoring in blast furnace internal high temperature zone, and the temperature survey of similar operating mode; The device one-piece construction provides mechanical protection for thermopair, can prevent effectively that high-temp. furnace material is to the destruction of thermopair; With cooling system, can improve protective device self life and reliability, guarantee that it is to long-term effectively protective effect of thermopair; Between protective device and the thermopair provision for thermal insulation is arranged, can guarantee as a result correctness of thermocouple measurement.
